In reply to Chive Talkin\':
By next year, we will not be just talking about the Pfizer vaccine. There are many more in the possible pipeline, and as far as I know, most of them also target the envelope spike proteins, which is what that vaccine is based on. It therefore follows that the other vaccines could well be just as useful (though not necessarily so).
So the supply will increase as more vaccines become approved, thence procuring vaccines for this country will become easier, especially since the government has done deals for more vaccines than we require, with different companies. (I am not a government supporter, I'm just going on what has been said in the news over the last several months).
Thus there should be less trouble getting vaccinated heading further into the middle of the new year; BUT we haven't even got this first vaccine through all testing yet.
